Keeping a sprite rotated correctly (disabling rotation)

I'm new to the library but am developing a platform based game similar to commander keen and would like the physics engine to control the players movement, but would like for the player to not rotate during movement. (i.e. the player will remain upright
at all times)

You can do this in Blend as well, in the PhysicsObjectBehaviour Properties. It is called "MomentOfInertia" there. The higher the value, the less the object will rotate. Infinite will prevent rotation completely...
